The answer will depend on whether the depth is in feet or inches or some other units.
84.16 US gallons
To answer this question, you can calculate the volume of the cylinder in cubic inches, then use the fact that a gallon is 231 cubic inches to convert to gallons. Cylinder volume is the cylinder base area (the circle that is 12 inches in diameter) times the height. Cylinder base area: 12 inch diameter, using pi x r2 = 3.14159 x 62 = 113 in2. Cylinder volume: 113 in2 x 10 ft x 12 in/ft = 13560 in3. Conversion to gallons: 13560 in3 (divided by) 231 in3/gallon = 58.7 gallons.
This cylinder will hold up to 19.65 gallons of water.

One gallon.
About 38.82 gallons for every inch deep .
A cylinder with a diameter of 19 inches and a height of 12 inches can hold up to 14.73 gallons of water.
The volume of the cylinder is πr²h, which works out to 339.292 cubic inches, or 1.469 U.S. gallons. (One gallon is exactly 231 cubic inches.) Note that the answer is different if you use Imperial gallons. That's just one more reason to go metric!
